This “upgrade” will be rolled out to PCs, tablets, smartphones, the Xbox One console, Microsoft HoloLens, and Internet of Things (IoT) devices. It will make its debut on August 2, just days after Windows 10 celebrates its first birthday and after Microsoft pulls the plug on its free Windows 10 upgrade program.

NASA got one step closer to its mission of launching the Space Launch System (SLS) to Mars by this week putting the world’s most powerful rocket booster through its paces in a ground test at Orbital ATK’s test facilities in Promontory, Utah. Tuesday’s launch — as seen in the video and photo gallery accompanying this article — was the second time the rocket boosters have been tested in this way — and the last prior to lift-off in 2018 for a test flight with NASA’s Orion spacecraft, representing a key milestone on the much-anticipated Journey to Mars.

Does using a smartphone fundamentally alter the way that your brain works? While the jury is still out on the long-term effects of heavy cellphone use, a group of researchers at the Mayo Clinic recently discovered that text messaging elicits a change in the regular rhythm of brain waves, completely different than the waveforms created by any other activity. “The big deal with discovering this ‘texting rhythm’ is that the number of new brain waves that are identified on EEG (electroencephalogram) are extremely rare at this point in time,” said Dr. William Tatum.

Earlier in June, BMW announced a switch in the focus of it’s “i” sub-brand from efficiency to autonomous driving. Earlier this week BMW, chipmaker Intel, and machine-vision technology company Mobileye separately said the three companies will hold a joint news conference on Friday, according to Reuters. Without doubt, the purpose of the meeting will be to announce a partnership to develop self-driving vehicles. BMW has already said it will introduce an autonomous flagship model in 2021.
